So I've looked around a bit, and I am not able to find anything worthwhile, seeing as Brand A is loved by some and hated by others, and Brand B is loved by the haters of Brand A and hated by the lovers of Brand A.

Right now I'm rocking a pair of Sony MDR-V700's that I got for Christmas 4 or 5 years ago, and I'm looking to upgrade a bit. The sound quality seems a little flat, with a decent bass end, but everything else feels flat. I'm looking for a decent set of phones (Over ear or IEM's doesn't matter) that are pretty balanced, but still give me good bass. just wondering what my options are and if I could improve very much over what i have now.
